Application filed April 13, 1920. Serial No. 373,465.

To all whom z'tmay concern:

Be it known that I, Brennan N. Monrms,

a citizen of the United States, residing at' new and useful Improvementsin ()iLGas' Generators and Burners, of which the following is aspecification.

This invention relates to an oil-gas maker and burner and particularlypertains to that type of hydrocarbon burners embodying a retort and anarched conduit extending over the retort and connected thereto andhaving a burneropening arranged to direct flames against theretort. Inburners of this type, oil-fuel, such as kerosene or other hydrocarbonsis fed to. the retort preferably un der air pressure, and is convertedinto com.- bustible vapors by heating the retort, the vapors beingdelivered from the burner orifice and there ignitedto form flames whlchare directed downwardl a ainst the to of the retort with consi erahleforce. he flames are spread by the top of the retort and are directedagainst the upwardly extending portion of the conduit ordinarily withsuch force and heat as to injure the walls of the retort at the point ofimpin ement of the flames. An object of this invention is to providemeans for protecting the conduit against the destructive action of theflames so as to render the burner more durable. Another object is toprovide a construction in the retort of burners of the above characterwhereby pulsation of the flame is obviated and a substantially uniformfeed of the inflammable vapors insured.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which:

Flgure 1 is a View of the device in vertical section as seen on the line1-1 of Fig. 2. Fig. 2 is a view of the device as seen in side elevation.

Fig. 3 is a view in horizontal section as seen on the line 3-3 of Fig.1.

Fig. 4 is a view in horizontal section as seen on the line 4-4 of Fig.1.

More specifically 5 indicates the side wall of the retort which is bowlshaped and 6 designates the top wall thereof which is substantiallyflat. An arcuate or arched conduit 7 extends over the retort and isconnected at its ends thereto; one end of the conduit opening to theinterior of the re tort through the side Wall adjacent to the topthereof and the other end of the conduit communlcating through anaperture 8 with the interior of the retort adjacent to the bottomthereof. The inner wall portions of the conduit intersect with the'sidewall of the retort and extend upwardly therefrom on dlametrlcallyopposite sides of the top wall and normally would be subject to thedestructive action top wall as will later appear. for protecting jurediby the H jections intersection of the conduit with the retort and extendinwardly from the inner wall portions of the conduit to points spaced ashort distance. on the opposite sides of the center of the top wall;theadjacent ends of the projections being tapered as indicated at 10 toform flame spreading surfaces spaced from the conduit. An openig 11 isAsa means the conduit from being inames a palr of spaced proof flamesspread'by the,

9 are formed on the top wall at the provided on the underside of thearched portion of the conduit which is fitted with a nozzle 12 having aburner orifice 14 which opens downwardly opposite the center of the topwall of the retort, and a cleanout opening 15 is provided in the top ofthe conduit opposite the burner opening.

Means are provided for delivering a hydrocarbon fuel to the retort whichis normally closed by a plug 16 at a point near the bottom thereof,which-is here shown as embodying an opening 17 in the bottom of theretort in which a plug 18 is screwed; a feed tubal!) opening to theinterior of the retort through the plug. The tube 19 leads from anysuitable source of hydrocarbon supply, preferably being connected to apressure tank by which the fuel may be delivered to the retort underair-pressure.

Extending into the retort from a point above the aperture 8 is a baffle20 which is located on a plane beneaththe upper opening. leading intothe conduit and terminat ing above the fuel intake. .This baflle isordinarily submerged in the fuel within the retort'when the device is inoperation and serves to prevent-vapors formed above the surface of thefuel in the retort from entering the lowermost end of the conduit anddirects them solely through the uppermost end portion thereof. By thisconstruction a uniform discharge of vapors from the nozzle is caused totake place and a non-pulsating or steady flame is produced,

it having been'found that where the baffle is omitted and vapors formedin the retort are permitted to pass into the lowermost end of theconduit an irregular or pulsating flame is produced, as is the casewhere the conduit does not open at both ends to the retort.

Extending beneath the retort is a base plate 21 the ends of which areconnected to the retort through standards 22 and encompassing the retortis an asbestos wick 23 which rests on the base plate and passes betweenthe retort and the standards.

In the operation of the invention initial generation of the vapors iseffected by permitting a quantity of the fuel oil to flow out the nozzleon to the top' of the retort from whence it will flow over the sides ofthe retort on to the wick where it may be ignited; The heat resultingfrom burning the fuel on the Wick' will act to heat the walls of theretort so as to warm the oil content sufliciently to form inflammablevapors the generation of which will set up a pressure in the retort andcause a portion of the vapors to be discharged through the nozzle wherethey are ignited. The flames produced by the burning vapors will bedirected downwardly a ainst the top of the retort and will strilethereagainst at a point centrally thereof and midway between the flamedeflecting projections 9. The top of the retort will operate to spreadthe flames horizontally but they will be prevented from directlyimpinging on the conduit by the protecting projections which by reasonof being formed of a thick body of metal will endure the destructiveaction of the flames. The walls of the retort will be heated by theflames directed on the top thereof to such extent as to maintain thegeneration of the vapors and continue operation of the burner.

I am aware that hydrocarbon burners have hertofore been constructedembodying a retort and an arched conduit connected thereto and Itherefore do not claim this feature broadly; my invention consisting inthe particular improvements in the construction of generators andburners of this type as set forth in the following claim.

I claim:

In an oil-gas maker and burner a retort, an arched conduit extendingover said retort and having its ends connecting with the sides of theretort and opening thereto, a burner nozzle in the arched portion ofsaid conduit opening opposite the center of the top wall of said retortand a pair of spaced projections on the top of the retort arranged onthe opposite sides of the center thereof and projecting forward from theinner wall portions of the conduit at the point of intersection of thelatter with. the retort, said projections being formed with inclinedflame deflecting faces on their adjacent ends.

In testimony whereof I hereunto afiix my signature this 6th day ofMarch, 1920.
